The cost of installing ductless air-conditioning (split systems) in Australia varies depending on room size, system capacity, brand, and installation complexity.
Typical installed price ranges:
- Single split system (one room): from $2,000 – $3,500 AUD
- Multi-split system (2–4 rooms): approximately $6,000 – $8,000 AUD
- Whole-home multi-zone systems: can exceed $12,000 – $15,000+ AUD
Prices may increase if electrical upgrades, long pipe runs, or difficult roof access are required. Popular Australian brands include Daikin, Mitsubishi Electric, Fujitsu, Panasonic, and Samsung.
